SSL Computer ROMs (Recreating the Computer)

[mike_signo]

Hi guys, hope you’re all well.

I’ve been reverse engineering the SSL computer, and I found that besides the floppy, you also need a lot of data stored in the ROM inside the computer. I have a working unit, but I don’t have an EEPROM reader. Does anyone have EEPROM bin files saved that they’d be willing to share? It would help a lot.

On the plus side, I’ve got the computer running in a virtual machine. There’s still plenty of work to do, mainly because Total Recall is a separate computer and I can’t get it working yet, but I’m confident we’ll get there.

Thanks,
Michele

Hi Michele,

Great! We are also working on the same project with a colleague named Steve.
If we could exchange information, that would be a significant step forward.

A quick clarification: Most of the ROMs in the computer are those found on the NM4 boards and in the character generator for the VDU board...
The same applies to the "Total Recall" section...
One exception is the Ultimation interface board, which is built around an 8032 processor, with its program stored in ROM.

For my part, I have attempted to develop something similar using an Arduino's architecture, CAN Bus and a touchscreen.
I also thought that a "scribble strip display" would be a nice addition to the channel multiplexer board. (see the attached photos).

If we could pool our resources, that would be a very good thing. I am particularly curious about your "virtual machine."

With my best.
Pascal
